essere common to the use of mariners. When it is vdesired tolteep a' permanent record of theJ voyage, the pen may be suppliedj ivitliink 'from the reservoir or ink Welll, supported on the carrier,.and the pen 1"vill then trace `oil the actual course oi tliepvessel upon the The opcrationof the device is as follows:

The propeller is rotated by the aclion'oi the 4Water :it va rate according' to :the speed of the vessel. Thisl motionV is transmitted b v suitable.reduction gearing lo the transmission shaft which carries the friction cone. The friction i'ollers are adjiistably mounted in operative engagenient. with the friction ners chart graduated to degrees of latitudeA and longitude is carried on the face of the compass7 the chart havingr the proper course traced thereon. A pen or pointer carried by the movable carriage indicates on the chart when the true course is being followed. lhe friction driving element for the tracing mechanism is adjusted so that as the vessel advances one mile, a like proportionate dis tance is traversed by the pen across-the conipass chart and the pen thus indicates on the chart the exact location ot' the vessel athall. times, with respect to the latitude and lo'igitude. It thus is only necessary for the steersinan to hold the. vessel so that the pointer follows the course indicated on the chart, and as the proportionate rate of the 1vessel and the pointer is the saine, the true course may be adhered to Without requiring observations of the sun or noting the position of siirroundine,r objects. As the distance between the degrees of latitude and longitude var it is sometimes necessary to adjust the movable driving element t'or vthe tracing mechanism with respect to the driving cone, so that the proportionatespced of the vessel and tracingl apparatus shall always be the saine. lt will thus be evident that an ordinary person may be able With the use of this device to navigate a vessel over a desired course Without the exercise oi' any special skill, more than to steer the vessel according to the indications of the pointer.

lith the use of this instrument, it is not necessary to take the sun or to make nautical calculations as to the position of the vessel in longitude and latitude', as at any time such location may bedeterm'lned by reference to the position of the pointer on the chart, and the distance traversed may `loeascertained `equally as -Well by'relerence to the distance registering mechanism. By adjusting the in liing, needle the exact course will be actually traced 0H on the chart and this willprovo a checlrto show whether the liclinsman hasbeenfolloiving the true course. For the sake of convenience, as many of the `ii'idi'eators may be installed in the vessel as desired and in any preferred positions,

il -will be evident that niy invention may be 'applied equally as well to air ships, subnini-niesA and vessels of different character, or by slight niodilications, the priniciples involved could be applied to land vehicles.

'lhc invention is luirticularly useful for surveying purposes, following the coastline t'or instance. in siich case a blank chart laid oli' in the proper degrees of latitude and longitude would be engaged on the coinpassv disk, the hiking needle loe adjusted,and as the vessel proceeds, the course of the same would be duplicated on the chart, to serve Yt'or ful uro reference.

Frointhe foregoing description taken in connection with the drawings, the operation and advantages of my improved nautical recording ap'iaratus will be readily understood and appreciated and it will be apparent that v l have produced such a device, accomplishing all the results herein set forth as the objects of the invention, which is efficient, practical and satisfactory in every par-l tiulai'. i
